GENERAL INSTRUCTIONS
Mixing: Mix only with water. It will not mix with oil or diesel fuel. Mechanical or by-pass agitation in the spray tank is recommended, and it should be maintained during spraying.
Quarter fill the spray tank and add the required amount of herbicide in the following order: Wettable powder or water
dispersible granules; suspension concentrates (atrazine flowable); aqueous concentrates (e.g. Tordon 75-D, 2,4-D
amine); emulsifiable concentrates and finally surfactant or crop oil.
Adjuvants: DO NOT add surfactants (such as BS-1000) or crop oils (such as Uptake Spraying Oil) unless specifically recommended to do so in the DIRECTIONS FOR USE Tables, 1 and 2.

APPLICATION
Tordon 75-D may be applied by:
Ground boom. Spray using accurately calibrated equipment delivering 50 - 100 L water/ha. DO NOT use less than 200 L/ha in sugar cane. When treating maize and sorghum, the risk of crop injury will be reduced if dropper nozzles are used to avoid spraying the growing point of the crop. Misting machines and boomjet sprayers should not be used for treating crops.
Aircraft. Use accurately calibrated equipment to deliver not less than 20 L water/ha. DO NOT use less than 50 L/ha in sugar cane.
High volume. Apply using a calibrated handgun with D5 or D6 (2 - 3 mm) nozzle plate and operated at 400 - 500 kPa. Spray to thoroughly wet the weed, usually 2,500-3,500 L water/infested ha is required.
Stem injection. Treat only trees with good sap flow. Make injection cuts at 13 cm spacing around the diameter of the tree at waist height or at 15 cm spacing at ground level. The cuts should be made using a 5 to 7 cm wide narrow bladed axe. The cut must be made through the bark and deep enough to place all the chemical in contact with the sap wood. Treat each stem of a multistem tree where possible. Inject the chemical mix into each cut immediately after the cut is made. Apply the mix with a vaccinator or similar equipment which can be accurately calibrated or a tree injector which can apply the measured dose at or near ground level. Injection at or near ground level is essential in the Traprock area of south-eastern Queensland and is preferred for optimum results in Bimble box (poplar box) areas.
Cut stump. Cut the trees as close to the ground as practicable, leaving stumps no higher then 10 cm. Spray, swab or brush the chemical mix immediately to the freshly cut surface so as to thoroughly wet the surface. If the cut surface is oily, add a non-ionic wetting agent to assist penetration.
Frilling. Make successive overlapping cuts into the sapwood around the entire circumference of the base of the tree. Spray to thoroughly wet the frilled area.
Injecting spray into centre of weed. Inject using a vaccinator or similar equipment, 1 mL of treatment mix  into the growing point for each 2.5 cm of the plant stem diameter. (See Zamia palm).

COMPATIBILITY
Tordon 75-D is compatible with:
atrazine (600 g/L flowable or an equivalent granular product)
Dow AgroSciences (2, 4-D) Amine 625
diquat
metsulfuron-methyl
Topik
glyphosate 450
Ripper 480 glyphosate

CLEANING SPRAY EQUIPMENT
After using Tordon 75-D, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean any tank, pump, line and nozzle filters.
To Rinse: After cleaning the tank as above, quarter fill the tank with clean water and circulate through the pumps, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.
To Decontaminate: Before spraying sensitive crops (see PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS section) wash the tank and rinse the system, as above. Quarter fill the tank and add an alkali detergent at 500 mL/100L of water or the powder equivalent at  500 g/100 L of water) and circulate throughout the system for at least fifteen minutes. If using a concentrated laundry detergent use 250 g (or mL)/100 L water. Do not use chlorine based cleaners. Drain the whole system. Then remove filters, nozzles and clean them separately. Finally, flush the system with clean water and allow to drain.
Rinse water should be discharged onto a designated disposal area or if this is unavailable, onto unused  (and away from plants and water courses).

RESISTANT WEEDS WARNING
Tordon 75-D Herbicide contains members of the pyridine and phenoxy groups of herbicides. The product has the disrupters of plant cell growth mode of action. For weed resistance management, the product is a Group I Herbicide.
Some naturally occurring weed biotypes resistant to the product and other Group I herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by this product or other Group I herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Dow AgroSciences Australia Limited accepts no liability for any losses that may result from the failure of this product to control resistant weeds.
Strategies to minimise the risk of herbicide resistance are available. Contact your farm chemical supplier, consultant, local Department of Agriculture, or local Dow AgroSciences representative.
